the AA downpipe in your video was tested against a wall, which of course we know provide reverb, but the stock wasn't.
regardless was a good and useful video on comparing stock downpipe to a highflow downpipe
I just traded my 2020 M340 for a 2023 M240. I love my new ride but miss the sound of the 340. They keep making the cars sound worse for emissions sake. I live less than 30 miles from AA I need to go check them out. Sounds great!
Does all the revving BEFORE the valve opens...
I know right 🥴
😅
Stock is also pretty good!!!
What an informational video 👏
No CEL?
Awesome rear man! Superb looking!

I thought the Bosch ECUs for the 2021s are locked. ??
What color is this? It looks amazing!
It’s mineral grey with a nice wash
Just im goona say اللهم أرزقنا ياااا☝️ااارب
What kinda spoiler is that? Looks good!
Horry shat this color is the one!
Did you get a check Engine light on
Link to the diffuser?
Notice how even in sports + mode, smoke only comes out the left exhaust pipe. I still cant figure out why, even with coding the flap to be open at all times. Anyone have an answer to this?
Easiest way to do it, is ti turn on the car and put it in sport mode. Rev it a couple times till you hear the valve in the exhaust open snd go unplug the wire attached to the valve in the rear. It will then stay open always and will never close.
i have m340 i same shit but sometimes smoke comes from both holes and im kind a confused
@@damirshukurov792 Same. Never figured out why but everybody else has it so I started to worry less about it.
It helps the engine warm up once the engine warms up both valves open up. And an increase in back pressure gives more mpg
Stock exhaust has only one valve on the right side. The right side doesn't have a muffler and when the valve is closed, it routes all exhaust flow through the muffler.
Why did you turn the car off five seconds after the valve opened?
Great video!
Any turbo spool with catted downpipe?
Did you have to get a tune? or just install and you're good to go? did you just get the downpipe or did you also get the turbo flange gasket?
I have a JB4, no tune- no CEL. And I just got the Downpipe- I used the gasket from the old Downpipe.
@@nsfung10 thanks
@@nsfung10 U have jb4 but no tune? U meant no pro tune?
thats a beautiful car you got there.
btw can u get that spoiler from bmw itself?
This is an aftermarket autotecknic spoiler
Where did you get the spoilers, rear diffuse, and front lip? Do you have an IG I can look at more pics?
Spoiler is from autotalent it’s the autotecknic,
Diffuser is m performance from bmw dealership
and I don’t have a front lip or an IG sorry.
@@nsfung10 is the spoiler the dry carbon competition plus?
There is no cutting required for the installation, right? Also, can I use it just for sound without installing any software? Will it cause any harm to the vehicle or the turbo? Will the vehicle malfunction light turn on?
Right. Yes. No. Why would they sell something that harms the vehicle? And no.
Neighbours will luv ya
stock sport+ sounds the best.
just bought my m340i, where did you get that trunk lip?
It’s from Autotecknic
Congrats it’s amazing to modify and drive! 2020 or 2021? I heard the exhaust note has less pops and burbles in 2021- never seen it firsthand
@@nsfung10 it’s a 2020, it’s not super loud but it pops a ton. You can definitely hear them though.
What’s available for the 340d please???
What rims you rockin? Those aren't stock right?

Running 13 in front, 15 in rear. Need some lowering springs..
what size rims are those? Front and back.
It’s not aggressive
Front: 18x8
Rear: 18x8.5
@@nsfung10 Bet, Thx!
How is the name of the exhaust?
is this tuned
What wheels are those?
Wow so cool
Lol
Are you running spacers?
Yep 15 in the rear
@@nsfung10 awesome kid! What size spacers are in the front? I am going to put spacers on mine too soon.
Saw you on bimmerpost. Did you install the dinan exhaust yet?
Yeah I did, its pretty loud. Will upload some clips someday when I get the time.
@@nsfung10 Awesome I just ordered mine. Please tell me it's civil in comfort mode 🤞
@@iliketakingshowers the cold start is pretty terrifying (for my neighbors)
Any CEL with this catted downpipe? Are you tuned? Also, how much louder does it make the car? Hard to tell in the video
No CEL, no tune. this video is just hi flow catted down pile. And it’s a lot louder. I now have a dinan exhaust which makes this even louder.
@@nsfung10 bro, what do you think about mine? Getting a GESI 50225 cat, it’s 400cpsi, I have an MPE , my car is 2021.
Will the sound be a lot louder or not because of the cpsi?
Thanks in advance
Does remote start still work with down pipe??
@@nsfung10 can you post a video with the dp and dinan exhaust new sound?
@@chrisscmanski1715 Lol. Why wouldn't it?
Wich colour is this? It’s awesome
Mineral grey metallic
Do you have your m340i with opf
No I believe the older generations (I purchased the car in 2019) came without it and the stock burbles and pops were louder and more pronounced than the newer models
Ok thank you bro
Where did you get the diffuser?
It’s a BMW M performance part, I got from getbmwparts.com, but you should be able to find it from your dealership as well
@@nsfung10 do you have a part number?
@@droveokay1108 51-19-2-459-740
What’s the name of that gray ?
Mineral grey metallic
Where u from bro
Nyc
The wall will echo the sound better
Valves open at 2:06, guy turns car off at 2:11.... Give me a break lol.
What rims are these?

Hey bro do you get any in cabin smells? I'm catless and the smell is really bad, wondering if adding a high fliw would completely get rid of it. I drive my little bro around a lot and don't want him smelling that bs
Yeah I still get the smell, it’s not horrible. If I keep the air recirculating with out any outside air I don’t notice it.
@@nsfung10 same here but when it's wet out the windows fog up when I do recirculate, so I don't like using it. Looks like I'll have to go back to stock then, thanks for the help btw
@@nsfung10 Kinda surprised as it's Catted .
@@willjames734 ik im a year late, but what really helps reduce the smell in cabin is replacing that small gasket between the dp and turbo. It’s one time use so if not replaced could cause a small leak.
The wheels...are those 18s?
does that mess with the warranty at all?
Warranty is only void if they can prove a modification caused the issue.
Do you have a check engine light?
Nope
very small difference. I'm not doing this stupid downpipe change ;D It does not give anything but sound and +0.01 HorsePower more xD
Hi I no uk
Is that Nardo Gray?
its mineral gray
Thought Nardo Gray was an Audi color 🤔
Stock is much better
